Topic: WET3300SQ1 Water temp issues (Read 6539 times)

I tested the thermistor. It read about 65K at ambient ( about 65º) and decreased to about 20K as hot water was introduced. This seems about normal per the chart I found. I guess I need to change the ATC switch.

For now, I reversed the connectors on the hot and cold water valves, and things are more or less normal.

I checked once again....I have my cold water hose going to the upper fitting, which had the white connector, and hot water hose going to the lower connection, valve with red connector. And I double checked that in fact cold water is coming from the cold hose, etc. The problem must be in the machine

On the + side, I am getting really good at getting the top off! You have to pull it back a certain distance, twist if just so counterclockwise, and work it up. Reverse for putting it back on. The left side clip is interfered with by the side outlet vent discharge, but you can wiggle it "just so" to get it on!

Will whirlpool provide free parts to a homeowner doing his own repair? The machine is only a few months old, so I assume it would be covered by warranty if I called for service, but I just like to do it. Already, when he machine was just 2 weeks old, I had to replace the high limit temp switch on the dryer. All the exhaust is brand new free flowing, no issue with that. Maybe I just got a lemon!

Even if your selector switch says hot,the way your valve works you will not be able to fill your tub with only hot water.Sorry,welcome to conserving energy.Try explaining this one to a 70 year old lady,who's last washer would fill with hot water?

This is a great forum! I appreciate all the feedback. I can live with the mixing, but the biggest problem is that when I select flat out cold, it was coming in all HOT. As I mentioned, I have reversed the connectors on the hot and cold valves, and it works sort of, so I can get at least a cool wash. I am still leaning towards a bad ATC switch, and I may replace it just because. I would like to get it from Whirlpool, but am assuming I will probably have to spring for it. Looks like it runs about $26

This forum is incredible!!.I had contacted whirlpool by email, regarding the temp issue....do you think they shared this tech tip with me?? Fat Chance!

Although my model is slightly different than is listed...they list YWET3300SQ1, and I have WET3300SQ1. They show serial number to CW22. Mine is MW22. The W22 indicates year and date of manufacture. I thing the C and M indicate made in different plants. And the specific switches they show do not include my switch part number. NONE THE LESS...the problem is exactly what I was experiencing....confusion / reversal of H:C. I put the new switch in today. It is a rev D where the original is Rev C. I remain quite hopeful that this switch calibration issue was causing problems, and the new switch should fix it!!!!!!!!

I wanted to "figure out" the switch...took the old one apart, but it contains an integrated circuit, so all the voodoo is in there , and there is no figuring that out!
